Base64
Encode / decode text, URL, image
This tool encodes and decodes text, URLs and images in base64 and base64url. Handy for embedding an image as a data URI, debugging an API or reading an encoded string found in a file or token.
Encoding handles UTF-8 safely and everything happens in your browser: no data sent, no tracking, no ads.
